# WebDev-Dataset: 100 Full-Stack Web Apps for LLM Fine-Tuning

A fine-tuning dataset of **100 complete, working, multi-file full-stack web applications**.

Each sample contains a full project — backend routes, database schema, HTML frontend, CSS styling, and JavaScript — all in a single training example. This teaches a model to generate a whole working project, not just isolated snippets.

---

## Dataset Overview

- **Total Samples:** 100 unique full-stack web applications
- **File:** `dataset.json` (~462 KB)
- **Format:** Alpaca JSON (`instruction` / `input` / `output`)
- **Code:** Every sample is fully runnable with no placeholders or skipped logic

---

## Format

```json
[
  {
    "instruction": "Build a full-stack ... web app using Flask and SQLite ...",
    "input": "",
    "output": "<!-- FILE: database.py -->\n...\n<!-- FILE: app.py -->\n...\n<!-- FILE: templates/index.html -->\n...\n<!-- FILE: static/style.css -->\n...\n<!-- FILE: static/script.js -->\n..."
  }
]
```

### Fields

| Field | Type | Description |
| :--- | :--- | :--- |
| `instruction` | `string` | The prompt describing what app to build, the tech stack, and file structure |
| `input` | `string` | Always empty `""` |
| `output` | `string` | The complete multi-file source code |

### File Delimiter

Files inside the `output` are separated by:

```
<!-- FILE: path/to/file.ext -->
[source code]

<!-- FILE: path/to/another_file.ext -->
[source code]
```

---

## Tech Stack

Each app has 4-5 files:

```
├── database.py         # SQLite connection and table setup
├── app.py / main.py    # Flask or FastAPI routes
├── templates/
│   └── index.html      # HTML frontend
└── static/
    ├── style.css        # CSS styling
    └── script.js        # JavaScript (Fetch API)
```

- **Backend:** Python - Flask or FastAPI
- **Database:** SQLite3
- **Frontend:** HTML5, Vanilla CSS, Vanilla JavaScript (ES6+ async/await)

## Loading the Dataset

```python
from datasets import load_dataset

dataset = load_dataset("json", data_files="dataset.json")
print(dataset["train"][0])
```

---

## Fine-Tuning (Alpaca Format)

```python
def format_prompt(example):
    instructions = example["instruction"]
    outputs = example["output"]
    texts = []
    for inst, out in zip(instructions, outputs):
        text = f"### Instruction:\n{inst}\n\n### Response:\n{out}"
        texts.append(text)
    return {"text": texts}

formatted = dataset.map(format_prompt, batched=True)
```

Works directly with **Unsloth**, **LLaMA-Factory**, and any Alpaca-compatible trainer.

---

## Extracting Generated Code to Files

```python
import os, re, json

def extract_files(output_string, target_dir="./generated_app"):
    pattern = r"<!-- FILE: (.*?) -->\n(.*?)(?=(?:<!-- FILE:|\Z))"
    matches = re.findall(pattern, output_string, re.DOTALL)
    for path, content in matches:
        full_path = os.path.join(target_dir, path.strip())
        os.makedirs(os.path.dirname(full_path), exist_ok=True)
        with open(full_path, "w", encoding="utf-8") as f:
            f.write(content.strip() + "\n")
        print(f"Created: {full_path}")

with open("dataset.json", "r", encoding="utf-8") as f:
    sample = json.load(f)[0]

extract_files(sample["output"], target_dir="./my_app")
```
